Battery locomotive is mainly use for mining, it has common type, anti-explosion type and ground project locomotives, the battery locomotives are adopt IGBT chopped speed wave regulation and frequency convertor technology, has large torque, large traction, heavy load, high efficiency and save engery, less mainten, meanwhile has electric and air brake, locomotive performance is more safe and reliable. Good vision, suit for annual output of 1.2 million high methane coal mine use.

Locomotive is powered by batteries, the dc electric through converter inverter into voltage and tunable frequency three phase current, supply to two parallel AC traction motor, in the control circuit by the driver given instruction of the direction command and control Instruction, through converter and actuator on-off for pressure regulating, frequency control traction motor, make it satisfy the output control locomotive’s traction performance’s torque and rotate speed.

(2) Main loop

The main loop is consists of battery, dc circuit breaker, braking resistor, current transformer, three-phase ac asynchronous traction motor. Its working principle is as follows: when the locomotive in ready condition, the electricity through the resistor R1 to have battery charging to converter smoothing, when delayed, the touch light-activated thyristor SCR breakover. Later, in a certain control mode,transducer make the dc inverter into three-phase alternating current(ac).

(3). Control circuit

Control loop consists of controller, inverter, controller, etc. The locomotive control system main functions are:
